I’m currently using the Sociable Wordpress plugin on this blog. It’s a really nice, easy to use plugin that allows people to bookmark blog posts to sites like Digg, Reddit, StumbleUpon, etc. You can see it in action at the end of this post.

I’ve spotted a bug in the current version of the plugin (version 2.0) which prevents people from bookmarking your posts to StumbleUpon. If anyone tries to bookmark a page to StumbleUpon they will be taken to an invalid URL. The problem is with the following piece of code in sociable.php

'StumbleUpon' => Array(
'favicon' => 'stumbleupon.png',
'url' => 'http://www.stumbleupon.com/url/PERMALINK‘,

To fix the problem, change the above code to this:

'StumbleUpon' => Array(
'favicon' => 'stumbleupon.png',
'url' => 'http://www.stumbleupon.com/submit/?url=PERMALINK&title=TITLE',

You may want to temporarily disable the plugin whilst you make this change.
